5. MODES FOR CARRYING OUT THE INVENTION

Hereinafter, the embodiments of the present invention will be describedin detail with reference to accompanying drawings.

FIGS. 2 a and 2 b are a plane view and a side view of a hair extendingapparatus according to one embodiment of the present invention, andFIGS. 3 a and 3 b are a 3-D disassembly perspective view and a side viewof the apparatus respectively. FIG. 2 a is a 3-D plane view in which atop cover is not in a closed position and the adhesive tape cartridge isnot mounted on the hair extending apparatus.

The apparatus according to one embodiment of the present inventionlargely consists of a case 100, a head unit 200, and a deck unit 300.

The case 100 is configured of a wide front surface part which is exposedupward and a narrow knob part, where these parts are connected to makesmoothly curved surface. The knob part is configured of a lower case 110which is downwardly bended at a prescribed angle, a transparent topcover 120 for covering the wide front surface from above, and a knobcover 130 which is formed to conform to a knob part of the lower case110 to be connected with each other. The knob cover 130 and the lowercase 110 are screw-engaged to meet with each other through a screwreceiving hole 111 which is protruded. The top cover 120 is connectedwith the lower case 110 by causing an elastic depressing holder 121formed on left and right side of top cover to be hooked by a hooking jaw112 formed inside the lower case 110. Upon connecting the top cover 120with the lower case 110, it is preferable to have wide space enough toallow the deck unit 300 to be placed inside. The lower case 100 hasfinger receiving grooves 119 dented to prevent from sliding upongrasping the apparatus, as shown in FIG. 2 b.

The head unit 200 includes two revolving units 210, 220 of a prescribedwidth which are oppositely facing to each other and of which the facingsurfaces are planar and rear surface is curved, upper lids 211, 221,heating-element cases 212, 222, and lower plates 213, 223. Theheating-element cases 212, 222 are inserted into the open underside ofhouses 210 a, 220 a which are integrally formed with the revolving units210, 220, so that the heating elements 212 a, 222 a are held within it.The heating-element cases 212, 222 and the houses 210 a, 220 a haveoppositely facing surfaces exposed so that heats from theheating-element 212 a, 222 a may be delivered to the hair placed betweentwo revolving units 210 and 220. The heating elements 212 a, 222 a isrectangular-shaped plate of thin thickness, and the heating-elementcases 212, 222 are made of heat-resistant phenol resin. The revolvingunits 210, 220 are also made of heat-resistant PC (Poly Carbonate) forpreventing from deforming due to heat. Of course, the lower case 110 andthe knob cover 130 are made of PC.

And, dampers 212 b, 222 b are attached on a front surface of the heatingelement cases 212, 222, that is, a surface on which the heating elements212 a, 222 a is attached. The dampers 212 b, 222 b prevent heat of theheating elements 212 a, 222 a from being directly delivered into thehair, where the heat passing the dampers 212 b, 222 b is approximately150˜160 degrees.

The lower plates 213, 223 are clamped by a screw on a bottom surface ofthe revolving units 210, 220 in order to hold the heating-element cases212, 222 after the heating element 212 a, 222 a and the heating-elementcases 212, 222 attached with the dampers 212 b, 222 b are inserted intothe houses 210 a, 220 a. The top lids 211, 221 are combined with therevolving units 210, 220 by means of magnetic forces. For the purpose ofit, a magnet piece of a cylindrical shape is inserted into receivingholes 210 b, 220 b for the revolving units 210, 220 and thin iron piecesor iron components are inserted into corresponding portions of the toplids 211, 221.

The reason why the top lids 211, 221 is detachably attached to therevolving units 210, 220 via the magnetic forces is that it is easy toreplace new cartridge after using up all tapes since the paper tape withadhesive coated on outside for hair extension is mounted within therevolving units 210, 220. Also, what the top cover 120 is notscrew-engaged but hook-engaged with the lower case 110 is for the sakeof convenience in replacement of the adhesive tape cartridge. Since thehook engagement of the depressing holder 121 is released if thedepressing holder 121 is depressed inwardly, the top cover 120 can beeasily separated from the lower case 110.

A driven gear 210 c is attached to a rear bottom portion of therevolving units 210, 220, as shown in FIG. 4. The driven gear 210 c isattached in a lower position stepped from the bottom surface of therevolving unit 210. The step is necessary because a height of the drivedelivering plane which causes the driven gear 210 c to receive rotationforce from the deck unit 300 and a height of a plane on which atraveling path of the paper tape with adhesive coated on outside isformed are different. The driven gears 210 c, 220 c are rotatably heldby causing center-penetrating connection rod to be inserted intoreceiving holes 113 a, 113 b which are integrally formed with the lowercase 110.

The deck unit 300 includes a motor, various gears which are connectedwith one another, and caps, as well as a support plate 310 and a rackgear bar 330. FIG. 5 a is a disassembly perspective diagram showingcomponents of the deck unit 300.

Both sides of the support plate 310 is curve-shaped to mate with insideof the case 100, as shown in FIG. 5 b, and is screw-engaged with thelower case 110 through screw holes 311 formed in its surrounding andscrew receiving holes 114 integrally formed with the lower case 110.And, two pairs of screw receiving holes 312 a, 312 b are formed underthe support plate 310, and motors 31, 32 are screw-engaged via each pairof the receiving holes 312 a, 312 b as shown in FIG. 6. A first motor 31is connected via corresponding opening 315 predefined on the supportplate 310 under the support plate 310 with a portion being protrudedabove the support plate 310.

The driving gear 31 a connected to a axis of the first motor 31 isscrew-engaged with a trailing-edge linear gear 331 formed in the rear ofthe rack gear bar 330 of FIG. 7 upon combining with the lower case 110of the support plate 310. The secondary motor 32 has a reduction gearbox 32 a connected to its driving axis so that it delivers the reduceddriving forces to the driving gear 341 which is rotatably connectedunder the support plate 310.

FIG. 8 shows an arrangement of components connected to the support plate310, where components mounted above the support plate 310 are shown onthe right side and components mounted under the support plate 310 areshown on the left side as a basis of a vertical center line 1-1′.

The support plate 310 is rotatably connected to the driving gear 341, aswell as a pair of capstan gears 343 a, 343 b and a pair of deliveringgears 344 a, 344 b, and reverse rotation gear 342 for reversing rotationdirection and a pair of shaft gears 345 a, 345 b which are disposed inbilateral symmetry. A diameter and gear ratio of the pair of capstangears 343 a, 343 b are suitably determined as necessary to obtainrotation needed from axis rotation. The reverse rotation gear 342 isonly to reverse rotation direction and has 1:1 gear ratio with thedriving gear 341. The driving gear 341 is directly gear-engaged with onecapstan gear 343 a, and gear-engaged with the other capstan gear 343 bthrough the reverse rotation gear 342. Therefore, the pair of capstangears 343 a, 343 b (shaft gears 345 a, 345 b) may rotate in a oppositedirection to each other, for example one in clock-wise direction and theother in counter clock-wise direction, due to rotation of the drivinggear 341. According to embodiments of the present invention, a rightshaft gear 345 a may rotate in clock-wise direction and a left shaftgear 345 b may rotate in counter clock-wise in FIG. 8.

The shaft gear 345 a and 345 b has gear tooth formed on only upper edgeportion and a concentric circular hole of larger diameter than that ofthe pass-through hole of the shaft gear formed on a lower edge portion,as shown in FIG. 5 a and FIG. 6. The shaft 346 is inserted into thecircular hole, more specifically the rubber ring 346 a is first insertedinto the circular hole and subsequently into the pass-through hole 317formed on the support plate 310 in order to be hook-engaged internallywith the hub driving cap 350. Because hooking protrusions are formed inboth tip ends of the shaft 346 and a hooking jaw is formed within thehub driving cap 350, a hooking loop gets engaged with the hooking groovewhile being straightened after both hook protrusions of the shaft 346being passed by being pressed on the hooking jaw. A portion of outercircumference and inner circumference of the shaft 346 and the hubdriving cap 350 which face to each other is not circumferential butplanar by D-cutting so that the hub driving cap 350 may also rotate dueto the rotation of the shaft 346. Because a diameter of a lower portionof the hub driving cap 350 is wider than a diameter of the pass-throughhole 317, the shaft gears 345 a, 345 b are held on the support plate 310when the driving cap 350 are combined with the shaft 346.

After combination as mentioned above, if rotational force is deliveredto the shaft gears 345 a, 345 b, it is also delivered to the shaft 346due to frictional force of the rubber ring 346 a. The gear ratio of thecapstan gears 343 a, 343 b and the shaft gears 345 a, 345 b is set sothat the latter is larger than the former in terms of an amount of thepaper tap traveling when the capstan gear 343 a, 343 b and the shaftgear 345 a, 345 b rotate. As such, since the hub of the cartridgeconnected with the shaft gear 345 a or 345 b tends to wind a largeramount of paper tape than an amount of paper tape traveling due torotation of the capstan gear 343 a or 343 b, a difference between themcauses tension in the paper tape with adhesive coated. Since sliding mayoccur between the shaft gear 345 a or 345 b and the shaft 346 if thetension goes over the frictional forces caused by the rubber ring 346 a,it is preferable to maintain suitable tension in the paper tape wound.

The capstan gears 343 a, 343 b are connected into a pass-through hole313 formed on the support plate 310 via a connection pin 336 having acircular head together with the capstan 335 of FIG. 9. The capstan 335consists of a cylinder 335 a which is divided into 3 sections and twocircular iron pieces 335 b of thin thickness which are disposed betweeneach section. The iron piece 335 b is formed with saw tooth on an outercircumference, and the cylinder 335 a and the circular iron piece 335 bhave center holes with same inner diameter. The connection pin 336passes through the center holes, the support plate 310, and the capstangear 343 a or 343 b in turn, and then a stop ring 337 such as an E-ringis inserted into an annular groove 336 a formed in a peak head afterpassing all of them. A portion of circumference of the connection pin336 is subject to D-cutting, and an inner circumference of the capstangears 343 a, 343 b, the cylinder 335 a, and the iron piece 335 b aresubject to D-cutting. Therefore, as the capstan gear 343 a, 343 brotate, the capstan 335 also rotates. As the capstan 335 rotates, thesaw tooth formed in the iron piece 335 b move the paper tape withadhesive coated on one side while being clasped, thereby preventing fromsliding due to the adhesive coated.

Further, in the support plate 310, a release shaft 347 without gear ismounted on the support plate 310 in such a way to connect with arotation cap 351 after being inserted into another pair of pass-throughholes 314, as shown in FIG. 6. The rotation cap 351 has same structureof the driving cap 350 and is connected with the release shaft 347 inthe same manner to connect the shaft 356 with the driving cap 350. Therelease shaft 347 has a head with larger diameter than the pass-throughholes 314 integrally formed on its bottom edge to be hooked by thepass-through hole 314 upon being inserted.

Meanwhile, the driving cap 350 and the rotation cap 351 have thin ribs350 a, 351 a protruded from circumference disposed evenly in at leastthree directions, as shown in FIG. 6. They are responsible for beinghooked by an internal protrusion of two pairs of hubs of the tapecartridge with adhesive coated at the time of rotation, thereby drivingthe hub or rotating the hub while being engaged with it.

The support plate 310 is attached with the capstan sticking member 360which is closely contacted with the capstan 335 to be interposed by thepaper tape in order to deliver the driving forces of the capstan gear343 a, 343 b to the paper tape. FIG. 10 shows a structure of the capstansticking member 360. The capstan sticking member 360 is configured of ahousing 361, a roller 362, a stopper 361 of ‘

’ shape, and two rotational spring 364.

The roller 362 is configured of three pairs of discs 362 a with 2circular holes around circumference and up-and-down support rod 362 b.An axis of the discs 362 a is inserted into an up-and-down hole which isformed in one side edge of the up-and-down support rod 362 b. Thecapstan sticking member 360 except of the rotation spring 364 are allmade of plastic material so that the up-and-down support 326 b isrotatably held as the axis of three pairs of discs 362 a is insertedinto the up-and-down hole. An up-and-down pass-through hole formed inthe other side edge of the up-and-down support rod 362 b is aligned withan up-and-down pass-through hole 361 a formed in a tailing end of thehousing 361 and connected by a pin 318 a (shown in FIG. 5 a) that passesthe pass-through hole. Upon inserting the pin 318 a, the pin 318 a isheld not to be extracted by means of riveting after inserting the pin318 a into a pass-through hole 318 formed on the support plate 310 whilecausing a head 364 a of the rotation spring 364 with a hooking arm to beinserted. An E-ring is inserted between the pin head of the pin 318 aand the housing 361 to prevent the housing 361 from being extracted overthe pin. The pin 318 a serves as a rotation axis of the housing 361 anda roller 362 as a result of the connection. The capstan sticking member360 and the stop ring may be connected in turn after holding the pin 318a on the support plate 310 by means of riveting.

The up-and-down support rod 362 b is configured of a hooking rod 362 cconnecting up and down, as shown in FIG. 10. The rotation spring 364 isplaced between the hooking rod 362 c and an inner wall of the housing361 so that the roller 362 is subject to forces in a direction away fromthe housing 361 on the basis of the rotation axis, that is the pin 318a, due to elastic forces by which both arms 364 a of the rotation springis pushed. The up-and-down support rod 362 b has a small protrusionformed on its bottom surface so that the small protrusion is insertedinto a bottom surface of the housing 361 and hooked by a holding groove361 b formed on surface beneath the housing 361 when pressing the roller362 toward the inside of the housing 361. The holding groove 361 b isformed with a groove of a prescribed size along rotation path of thesmall protrusion on the basis of the rotation axis (pin 318 a) so thatthe small protrusion is entered up to the inside of the holding groove361 b when pushing the roller 362 inward the housing 361, and exited upto the outside of the holding groove 361 b due to elastic forces of therotation spring 364 when the push is released. If the capstan stickingmember 360 is mounted, the paper tape with adhesive coated on outsidemay be stuck to the capstan 335 by means of elastic force of therotation spring 364.

Further, as shown in FIG. 10, the housing 361 has a head end wider thana trail end into which the pin 318 a is inserted so that up-and-downsurface is trapezoid-shaped. Both sides of the head end of theup-and-down surface are protruded more than a boundary of the head endto form both guide protrusions 361 c. Such the guide protrusions 361 care responsible for guiding the paper tape that travels while beingcompressed between the roller 362 and the capstan 335. The paper tape isnot striped upward and downward by virtue of the guide protrusion 361 c.

A pair of parallel axis rod 361 d with pass-through hole is integrallyformed with the head edge of the housing 361. An axis 363 b which isvertically protruded in a lower portion of the stopper 363 is insertedinto the pass-through hole of the axis rod 361 d. Another rotationspring 364 is inserted into the axis 363 b before insertion of the axis363 b so that both arms of the rotation spring 364 can apply pushingforces to the stopper 363 after the stopper 363 is combined. If thecapstan sticking member 360 is pin-connected with the support plate 310,a hooking jaw 363 a protruded longitudinally under the stopper 363 iscaused to be placed above a rectangular groove 319 (FIG. 5 b) formed onthe support plate 310 when rotating the capstan sticking member 360around the connection pin 318 a while pressing a bending portion of thestopper 363 upwardly by fingers, and the hooking jaw 363 a is insertedinto the rectangular groove 319 by the rotation spring and the capstansticking member 360 is held in place when the press is released. Theelastic forces caused by the rotation spring 364 provided between theroller 362 and the housing 361 allows the roller 362 to stick to thecapstan 335.

The support plate 310 has a pair of semicircle protrusion 316 formed onits leading edge as shown in FIG. 5 b, and the connection rod mentionedabove in the description of head unit 200 is inserted into the apass-through hole 316 a located in the center, and a upper edge of theconnection rod is stepped to have a lower diameter than that of body sothat only portion of the upper edge is inserted into the pass-throughhole 316 a of the semicircle protrusion 316. If the support plate 310 isconnected with the lower case 110 by means of screw clamping, then theconnection rod serves as a fixed rotation axis, and therefore a drivengear 210 c of the revolving units 210, 220 may rotate around theconnection rod and subsequently the pair of revolving unit 210, 220formed integrally with the driven gear can also rotate around theconnection rod.

As shown in FIG. 7, the rack gear bar 330 is constructed of two parallelblocks of which an upper portion is bended 2 times, linear gears 332 a,332 b are formed in left and right side of the leading edge, and thelinear gears 332 a, 332 b are gear-engaged with the driven gear 210 c ofthe revolving units 210, 220. Therefore, the driven gear 210 c rotatesleft or right by forward-and-rearward movement along longitudinaldirection of the rack gear bar 330 thereby causing the revolving units210, 220 to be open or closed by any degree that is predefined indesign.

Directional plates 333 a, 333 b are vertically formed on a bottom ofeach of the parallel blocks of the rack gear bar 330. They are insertedinto two guide pair-wall 116 a, 116 b formed on a bottom of the lowercase 110 in order to prevent the rack gear bar 330 from being deviatedat the time of forward-and-rearward movement. The rack gear bar 330 issupported and slid on two guide pair-wall 116 a, 116 b (shown in FIG. 3a). When the rack gear bar 330 is mounted and a distinct press bar isplaced over it, the rack gear bar 330 is screw-clamped to twoscrew-clamping holes 117 through screw-groove in both edges of the pressbar, thereby preventing the rack gear bar 330 from being deviatedupwardly.

As shown in FIG. 8, in the lower case 110, a PCB 500 mounted with adriving circuit is provided below the support plate 310. The PCB 500 ismounted with the driving circuit of FIG. 11, including microcomputer 501having program embedded for controlling the motor 31, 32, a first and asecond drive unit 502, 503 for applying the driving power necessary forthe motors 31, 32, a power transistor unit 504 for supplying current tothe heating elements 212 a, 222 a, a power switch 510 mounted above theknob cover 130, an operational switch with hooking jaw mounted on abottom surface of the lower case 110, a mode switch 506 for specifyingautomatic/manual operational mode and a traveling on/off switch 508which each are mounted on both side of the power switch 510 above theknob cover 130, and a limiter switch 507.

To the driving circuit is applied DC voltage of 12V via connection jackprovided in the trail portion of the lower case 110 and the knob case130 by external AC-DC converter. The limiter switch 507 is inserted intoa switch groove 118 formed in a leading edge of the lower case 110. Thelimiter switch 507 is a type of the tap switch and its tap is providedtowards inside of the lower case 110. The tap of the limiter switch 507is pressed by a leading edge of the rack gear bar 334 when the rack gearbar 330 moves forward.

Hereinafter, it will be described on the adhesive tape cartridge mounteddetachably on the hair extending apparatus.

FIG. 12 is a disassembly perspective view according to the presentinvention showing the state in which a paper tape with adhesive coatedon one side is not wound. The cartridge 400 largely consists of a flatlower cover 410, a pair of wound hub 420, a pair of supply hub 421 and afat upper cover 430. Initially, a pair of paper tape roll with adhesivecoated on outside is wound onto the pair of supply hub 421 respectively,and the paper tape is connected to the pair of hub 420 to be woundwithout adhesive. According to one embodiment of the present invention,polyester is used as the adhesive. The adhesive is coated only onoutside of the paper tape. This is to deliver heat carried by theheating elements 212 a, 222 a to the adhesive via the paper tape,thereby causing the adhesive to be melted evenly across overall regioncontacting with the dampers 212 b, 222 b.

The lower cover 410 and the upper cover 430 are bilateral-symmetric anda center of both sides is dented inward so that the capstan 335 on thesupport plate 310 is allowed to be placed in the dented portion when thecartridge 400 is placed on the support plate 310. The lower cover 410and the upper cover 430 are screw-engaged after disposing the hubs 420,421 inside. For purpose of screw-engagement, the lower cover 410 has acolumn 411 with its center protruded, and the upper cover 430 has acircular dented portion 431 with a screw-hole formed at its center. Thelower cover 410 and the upper cover 430 are combined by inserting ascrew into the screw-hole of the dented portion 431 and the screw-holeformed in an upper edge of the column 411.

The column 411 has two protrusions be formed in bilateral symmetricalpositions, and the protrusions are inserted into two holes 431 a formedto conform to the dented portion 431 when combining the lower cover 410with the upper cover 430. The protrusions combined as such forms a pairof holding rods, where the protrusions are inserted into both internaledges of a shoulder 40 a of an iron pin 40 which is bended as shown inFIG. 13 so that the iron pin 40 is held between the column 411 and thedented portion 431. At this time, both arms 40 b of the iron pin 40apply lateral force in an outward direction (Da in FIG. 13) to push thepaper tape wound onto the supply hub 421 toward its center. This is formaking an unwound direction forward (that is, direction towards insideof the revolving units 210, 220) and stripping the paper tape only bytension force caused by certain resistance, when the paper tape woundonto the supply hub 421 is stripped. A waist 40 c of the iron pin 40 isbended more inside than both arms 40 b in order to make lateral forcemore intensely.

The lower cover 410 and the upper cover 430 has stop jaws 412, 432integrally formed on forward left and right edge, which are verticallyformed from the cover surface to face to each other. The stop jaws 412,432 form boundary wall not to be pushed outside of the cartridge 400when the paper tape is wound onto the wound hub 420 via inside of therevolving unit 210 by rotational force of the capstan 335. The lowercover 410 and the upper cover 430 have vertical connection protrusions413, 433 formed integrally therewith, which face to each other on leftand right side of front, rear and center portion. One pair of connectionprotrusions 413, 433 is combined in such a way to connect at top edgeswith each other, which serves as a holding rod. Since the protrusionsinserted into grooves of corresponding protrusions for connecting theconnection protrusions 413, 433 are stepped not to be inserted beyondit, a height of the pair of corresponding protrusions is a little higherthan that of the hub 420, 421. This is for the purpose of supporting thelower cover 410 and the upper cover 430, thereby to allowing the hubs420, 421 to rotate within the cover 410, 430 without friction.

The lower cover 410 and the upper cover 430 have four circular openings415, 435 respectively into which one pair of wound hub 420 and one pairof supply hub 421 are inserted. A diameter of the circular openings 415,435 is a little larger than that of circular steps 420 a, 421 a formedon upper and lower surfaces of the hubs 420, 421. Subsequently, the hubs420, 421 are allowed to be placed into the circular openings 415, 435correctly and the circular openings 415, 435 function as a rotation axisfor the hubs 420, 421. Further, a height of the circular steps 420 a,421 a is lower than or equal to that of the lower cover 410 and theupper cover 430. This is for the purpose of excluding a possibility tooccur rotation resistance which results from contacting with otherposition since the circular steps 420 a, 421 a of the hubs 420, 421 areprotruded outside of the cover.

The upper cover 430 has a pair of pressing wall 436 of a prescribedheight which has a T-shape in a sectional surface on bilateral side ofan opposite surface to the surface connected with the lower cover 410.The pressing wall 436 enables the cartridge 400 in place not to moveupward and downward upon being pressed by the upper cover 120 as theupper cover 120 is combined with the lower cover 110 after the cartridge400 is placed on the support plate 310 and also enables the cartridge tobe pulled from the apparatus by gripping the pressing wall 436 byfingers.

Hereinafter, the hair extending apparatus having aforementionedstructure will be described.

Firstly, it is preferable to open the top cover 120 and both top lids211, 221 of the revolving units 310, 220 and then assemble the adhesivetape cartridge 400. At this time, the driving cap 350 and the revolvingcap 351 are inserted into center of each hubs 420, 421 of the cartridge.And any amount of the adhesive tape is pulled out so that it is placedon a traveling path within the pair of revolving units 210, 220. Thecapstan sticking member 360 is rotated in both side of the apparatus byhook-releasing operation of the stopper 363 so that it may accommodatespace for use in placing the tape within the cartridge 400, and then thecapstan sticking member 360 is reversely rotated so that the roller 362is stuck to the capstan 335 interposed by the adhesive paper tape whilebeing hooked by the stopper 363. It is preferable to close both top lids211, 221 of the revolving units 210, 220 if it finishes disposing theadhesive tape on the path of the tape. FIG. 14 is a plane view of astate in which such procedures are completed. If it completes placingthe cartridge 400 as shown in FIG. 14, the top cover 120 is allowed tobe place over the lower case 110.

Upon pressing the power switch 510, the power is applied to the drivingcircuit of FIG. 11, and therefore is applied to the heating element 212a, 222 a through the power transistor 504 to form heat so that themicrocomputer 501 may carry initial operations. For purpose of theinitial operations, the microcomputer 501 can drive a first motor 31 ina forward-moving direction of the rack gear bar 330 through the firstdrive unit 502. As the rack gear bar 330 moves forward, a head of therevolving units 210, 220 is broadened by rotating the driven gear 210 cformed in the pair of revolving units 210, 220. Further, if the limiterswitch 507 is pressed as the rack gear bar 330 moves forward, itselectrical signal is changed. Since the microcomputer 501 stop drivingof the first motor 31 by recognizing the change, the revolving units210, 220 are in an initial state (OO′ of FIG. 14) broadened by aprescribed degree.

A user may select manual mode or automatic mode by operating the modeswitch 506 if necessary. First, it will be described on a case in whichthe traveling ON/OFF switch 508 in ON along with the automatic mode.

In automatic mode, the user may press the operational switch 505 onetime while placing artificial hair and real hair between the revolvingunits 210, 220. Then, the microcomputer 501 rotates the first motor 31in a reverse direction. Subsequently, as the rack gear bar 330 movesbackward, the revolving units 210, 220 are come into contact each other.This state remains for 2˜3 seconds. During the operation, the heat fromthe heating elements 212 a, 222 a is delivered to a pair of paper tapethrough the dampers 212 b, 222 b so that adhesive coated on the tape ismelted in both of artificial hair and real hair to extend. If it elapsesthe time, the microcomputer 501 causes the revolving units 210, 220 tobe broadened by moving forward the rack gear bar 330 until the state ofthe limiter switch 507 changes by driving the first motor 31. At thistime, the user can place other artificial hair and real hair betweenthem after pulling out the artificial hair and real hair extended by theadhesive.

If the revolving units 210, 220 are broadened, the microcomputer 501rotates the second motor 32 via the second drive unit 503. If the secondmotor 32 rotates, its rotation force is reduced by the reduction gearbox 32 a to deliver it to a pair of capstan gear 343 a, 343 b and a pairof shaft gear 345 a, 345 b through the driving gear 341 respectively.The corresponding gears (capstan gear and shaft gear) in left and rightside rotate in an opposite direction to each other by means of thereverse rotation gear 342. The capstan 335 and each of the wound hubs420 within the cartridge 400 may rotate due to this rotation, whichresults that any amount of the adhesive tape roll is pulled out from thesupply hub 421 and is wound onto the wound hub 420. At this time, awound length is nearly same as a width of the dampers 212 b, 222 b. Thisis for purpose of moving just only section of the paper tape withadhesive melted due to contact of the damper 212 b, 222 b and supplyingthe paper tape with new adhesive for next use. If such wining operationhas been completed, the hair extension operation in the automatic modeof one time is completed, and if the user presses the operational switch505 once more, above-mentioned operation repeats.

If the mode switch 506 is a manual mode, and the traveling ON/OFF switch508 is ON, the microcomputer 501 causes the both revolving units 210,220 to be engaged by moving backward the rack gear bar 330 upon pressingthe operational switch 505, and then remains this state until thepressing of the operational switch 505 is released. If the pressing ofthe operational switch 505 is released, the microcomputer 501 movesforward the rack gear bar 330 until the limiter switch 507 is ON andwinds the paper tape by a predetermined amount as described above.Therefore, the heat is applied to the adhesive tape while the userpresses the operational switch 505 in a case of the manual mode.

If the traveling ON/OFF switch 508 is OFF in both modes which areearlier mentioned, the microcomputer 501 does not drive the second motor32 and therefore does not wind any predetermined amount of the papertape even though the heat is applied to the paper tape byforward-and-backward moving operation of the rack gear bar 330. That is,a section of the paper tape in which the adhesive is melted off is notmoved.

This operation is used when separating the artificial hair and the realhair which are connected by the adhesive hardened. That is, by pressingthe operational switch 505 once more, it is possible to melt theadhesive and therefore separate the artificial hair from the real hairby applying heat to a connection part of the artificial hair and thereal hair extended via the section of the paper tape with adhesivemelted.

The hair extending apparatus mentioned above as limited embodimentsaccording to the present invention enables unskilled man to extend theartificial hair and the real hair easily and to present various hairstyle, and enables skilled man to extend larger amount of artificialhair and real hair within shorter time than prior art apparatus.Further, it is possible to separate the extended hair easily using theapparatus.
